CHURN AND FREEZER."

Specification of Letters Patent.

Patented. May 26, 1908.

Application filed February 17, 1908. Serial No. 416,362.

To all whom it may concern:

Be it known that I, ROBERT COMMON LAMBIE, a citizen of the United States, residing at Austin, in'the county of Travis and State of Texas, have invented a new and useful Churn and Freezer, of which the following is a specification.

My invention relates to an apparatus which with slight change may be used either as an ice cream freezer or as a churn; and has for its object to rovide an apparatus of this type whichsha-l be simple, economical and expeditious in its operation of making both ice cream and butter.

With this and other objects in view the invention consists of the novel combination, construction and arrangement of partshereinafter described and claimed.

In the accompanying drawings, illustrating the preferred embodiment of my invention; Figure 1 shows a side elevation, partly in section thereof arranged as an ice cream freezer. Fig. 2 is a like view with the up er portion of the machine omitted, disclosing the same adapted as a churn. Fig.3 is a section taken on the. line aa of Fig. 1. Fig. 4 is a broken detail section disclosing a clamping device for the retention of the'secti'ons of the two part supporting frame in position;

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawin s.

In carrying out my invention li employ an outerrece tacle 1, supported in position upon a suitable. ase, or directly upon the floor, said receptacle having a suitable cover 1.

As shown in Fig. 1, wherein the device is arranged as an ice cream freezer, 2 represents a can having a suitable cover 3, which can has upon the under side of its bottom a round pivot extension 4 bearing in a socket 5 formed in an upstandin central bossor rojection 6 secured to or formed with the hot tom of the receptacle 1. Said'can has arranged therein a dasher 7 comprising a preferably rectangular upright frame 8, through which passes a shaft 9 havng its lower end provided with" an angular terminal 10 bearing in a socket or step 11 formed in an n standing central-elevation orboss 13, said socket being of corresponding outline with said angular terminal to provide for the rotation of said can by the action of the shaft 9 as presently seen. Said dasher frame 8 is eauipped with lateral pivoted wm s 14 a apted to move in close contact with the an inner angular portion additional frame tents into ice cream. Said shaft 9 has at a:-

point above a sleeved extension of the frame 8, an angular terminal 15, said terminal engaging a corresponding socket, 15 in the lower end of an additional shaft 16 having at its up )cr end a miter gear or pinion 17 engaged y a vertical corresponding gear wheel 18, whose shaft 19 bears in the up section 20 of the supporting frame, the lower section of said frame being secured to a suitable base or floor, said shaft 19, also, being suitably actuated by a handle 21 by which means the motion' is manually imparted to thefreezer can.

A sleeve 22 having a bore of angular outline is slipped u on the up er corresponding end .or termina of the s eeve 22 of the dasher frame 8 and also. upon a'sleeve extension 23 of a miter gear or pinion 24 through which loosely passes the shaft 16, said miter gear or pinion intermeshing with the drive gear wheel 18, and whereby, it will be noted, that motion is transmitted to said dasher frame. Said sleeve 22 is provided with'a set screw 25 for the attachment of saidsleeve to the sleeve extension 23 of the pinion 24,

whereby said sleeve may be readily removed from said pinion sleeve.

Said sleeve 23 has 26 which is interposed between the lower end of thesleeve extension 23and the upper end of the sleeve extension 22 of the dasher frame 8, the purpose of which is apparent. Suitably pivoted in the upper frame section 20 is a dog 27 which engages interfitting a ertured extensions 28 and 29 projecting om said frame sections, respectively, and whereby said frame sections are adapted to be wedged together firmly in place, as in assembling the parts of the frame in position for use.

It will be noted that in adapting the machine for a churning operation, the can 2 is removed and in lieu thereof is substituted an member 30 which has on the lower side of its bottom cross piece a. rounded pivot-projection 31 which is adaptedto be inserted in the socket 5 of the step 6 of the receptacle in lieu of the can pivot extension 4 as above noted. Said frame has in then per surface of said lower cross bar an angu ar socket 32- which receives the corresponding terminal of the shaft 9; The upper cross bar of said frame 30 has an aperture through which passes the sleeve extension 22* of the inner .dasher frame 8.. Said i the bottomthereof and rotate the member, a i

second shaft in line with the first named dasher frame 30 has an annular aperture 33 in its upper cross bar which passes the corre. sponding surface of the shaft 9, and whereby, it will be seen, that on actuating the handle shaft 19, said outer dasher'frafne will be actuated together with the reverse actuation of the inner dasher frame 8, as in performing the churning operation.

It will be noted from the above that I have provided a machine which is adapted, as before observed, for readily performingthe operation of an ice cream freezer or churn, and which consists of; the minimum number of parts for carrying out said purposes, while it is easilyconstructed andreadily operated, as well as ex editious in action.

It will e understood that'latitude is allowed herein for making changes in the various details of the above 'describedparts without-departing from the spirit of my, invention.

I claim r V 1". An'apparatus of the class described, comprisinga nonrotatable receptacle with a socket in its bottom, a rotatable member within said receptacle having a pivot pin seated in sai'dsocket, a central shaft within said rotatable member arranged to engage shaft. and separately connected thereto, a

.fixed' toothed-wheel and a loose. tooth-wheel on said second shaft means for rotating said toothed-wheels in'opposite directions, a rotatable agitating member in said rotatable member provided with a sleeve surrounding said first named shaft and forming a bearing for the upper end of said rotatable member, a sleeve on said loose toothed-wheel, and an intermediate sleeve connecting the sleeve on said loose wheel to the sleeve on the agitating member.

2. An apparatus of the class described comprisinga two-part separate frame, a non rotatablereceptacle supported by the lower part of said frame, oppositely rotatable members in said receptacle, a vertical shaft carrying a fixed toothed-wheel for rotating one of saidjmembers, a loose toothed-wheel rotatable in opposite direction to said shaft mountedthereon and connected to the other rotatable member,'a toothed-wheel mounted on a shaft carried by the u'pper part of said two part frame and gearing with said fixedand loose wl'leels on said vertical shaft,interfitting apertured plates on adjacent parts of the separable frame, and a pivoted dog adapted to engage in said aperture and hold the frame parts together. i

In testimony that I claim the foregoing as my own, I have hereto affiXed my signature in the presence of two witnesses.
